Greddy Oil Cooler
 

Purchased this product from CounterSpace Garage and haven’t seen much information on it so figured some may be interested in seeing some pics and getting some information.

CounterSpace Garage has provided great customer service thus far, and I’d not hesitate to buy from them again, especially given their experience. This is not an ad for them, though. I paid full price for the oil cooler.

Anyway, here are some initial pics and thoughts. I only have a little bit of time to work on the car right now so don’t have a full install tutorial and will simply share what I have noticed so far.

Here’s the area where it will sit. It’s offset to the passenger side and looks like it will have minimal negative impact to condenser/radiator airflow.

Here’s the area behind where the cooler sits. The only obvious space for air to flow after exiting the cooler is noted by the arrow. I’m sure it would add a lot of cost, but I wonder if a vent in the wheel well might make any difference?

And here are some close-up shots of the cooler itself with shroud installed.

(Note that I have the bracket installed backwards here, and in the following shots I have the fins covered with tape to prevent damage before installation.)

The kit comes with foam for all 4 sides of the cooler where it meets the shroud.

The buttonhead fasteners are a nice touch with the shroud. I assume they are better for airflow, though I can’t imagine how much.

Hardware comes complete.

The only issue I’ve noticed so far is that 2 of the bolts are too short to fit with the bracket installed. I had some extra bolts laying around, which are slightly too long, but better than too short.

The kit comes with this bracket which slightly rotates the washer fill neck.

I haven’t finished the install yet, but the lines will run in the same configuration of other front mount coolers.

The horns get relocated, and you have to free the ambient temp sensor from it being taped together with the horn harness, but those are the only real non “bolt-on” issues I’ve noticed, which are very minor.

The instructions are all in Japanese, so you have to look at the pictures and then sort of figure things out from there [emoji848]

It looks similar to my Blitz oil cooler. They are very effective to the point that it may need to be blocked in cooler conditions. But you're in FL so it probably wont be a concern.lol

I live in the high desert of SoCal, and I still think my Blitz needs a block-off for street use. I've never seen it over 200F on the street with ambient temp over 100

Same here. 95F and 90% humidity barley cracks 180F. I could easy get to 230F+ before the oil cooler. I dont worry about thinner 0w20 anymore that's for sure.

Sounds like the Blitz unit has a 180°F thermostat like the Greddy unit. I’m considering asking Greddy if they have a thermostat with a higher opening temp.

Like you all said, though, a 180-200°F temp with 0W20 oil should be fine on the street.

I think as a gross rule of thumb you want to get the oil to at least 212F during operation to help boil out any water that inevitably gets absorbed into the oil.

That's why a block-off plate is advisable.

Clean install so far! It's amazing how, in our engine bays, there appears to be a lot of empty space but when you try to install something there's always something else in the way. Maybe all engines are like that?

I always wondered how this compared to the Jackson Racing Kit, in terms of efficiency and 2017+ friendly install.

Maybe @CounterSpace Garage or @CSG Mike can chime in.

The airflow primarily goes up behind the headlight, and exits out toward the back of the engine bay. :thumbsup:

Your temps are post-cooler; you can safely add 30-40F to get a pre-cooler temperature reading.

Water will evaporate off, even under 212F!

That said, if you have moisture in your oil, you got way bigger problems to worry about.

This is more effective than the JR kit, but costs a bit more.

Worth every penny.

Thanks for chiming in, CSGMike, and for the education and information.

The Greddy kit uses a different thread for the oil filter so the OEM filter doesn’t fit. Greddy makes their own filter, but any filter with the correct specs will work.

Attached is pic of the filter housing with rough measurements for ID and OD. Based on a phone call with Fram, it appears that a 3614 will work, or whatever cross references with that in your favorite brand.

I haven’t verified figment yet since I’ll be using the Greddy filters for the time being, but wanted to provide the information for anyone who’s interested.

Double post by accident.

As seen here, the stock Subaru filter should work OK.

Thanks, Joon525. I’m confused, though, because multiple sources have confirmed that the OEM filter doesn’t work. I have an extra Toyota filter, and will try to spin it in and see if it fits.

Hmm, maybe that guy I linked to used a smaller sized OEM filter (it looks like the wider one to me though). That could be possible since the OEM filters come in different sizes. So you may not be wrong afterall. Regardless, more info is sure to be helpful for other members.

As far as I'm aware, the OE filter threads into uses a M20 x 1.5.

The Greddy plate adapter changes the thread to 3/4"-16 UNF. It is stated on the Greddy website that the oil cooler kit "requires use of QX-1,3, SX-1,3 oil filter," which when identified on their product inventory is a 3/4" threaded filter with 65mm diameter. It looks like "O" part numbers have replaced Q or S. Google searches for inventory QX/SX turn up 3/4" / 65mm as well

Here’s a screenshot from Fram.com with the XG3614 filter as search criteria:

Based on the specs, I believe it will work. It’s 3/4 thread, has an anti-drainback valve, and the ID and OD of the gasket looks like it’ll fit on the filter housing.

Good catch.
I wonder what filter the guy in the post I quoted is using? Maybe it's NOT a Subaru filter afterall?

Updating the post with some finished pictures.

And after some further research, I believe the Fram 2951 will fit. I’ve ordered one and will verify fitment probably sometime next week.

Front bumper cover mostly back on for final shot. Had to remove a trim piece behind the bumper and trim the oil cooler shroud to make it fit behind my 2017 bumper. But otherwise everything fit well.

I contoured this to the shape of the bumper cover, and added some weatherstrip to make a seal.

Can confirm that the FRAM 2951 fits. Gaskets match up as well. The FRAM is about 3” diameter, which is the maximum that will fit.

Realized that I never explained what needed to be trimmed. Here is the section of the shroud that needed trimming to fit behind my 2017 Toyota 86 bumper cover:

And here is a rough representation of the trimming needed:

And here again the a close-up of that section looking through the front bumper cover, with some foam to seal the bumper cover to the shroud:

Water evaporates out of oil, even at less than 212F. You can see an example of this when you boil water on the stove; you'll see vapors before the water is actually boiling.

Oil temp readings from the 86 are ***post cooler***. Your oil is certainly hot enough pre-cooler! :thumbsup:

:thumbup:

Wow, the Greddy cooler with the shroud looks like it's probably more effective than the JR design. Very nice. My JR is keeping up with temps nicely here in Texas, at least NA.
